Deciphering the senescence-based tumoral heterogeneity and characteristics in pancreatic cancer: Results from parallel bulk and single-cell transcriptome data.

The prevalent intra- and intertumoral heterogeneity results in undesirable prognosis and therapy failure of pancreatic cancer, potentially resulting from cellular senescence. Herein, integrated analysis of bulk and single-cell RNA-seq profiling was conducted to characterize senescence-based heterogeneity in pancreatic cancer. Publicly available bulk and single-cell RNA sequencing from pancreatic cancer patients were gathered from TCGA-PAAD, PACA-AU, PACA-CA, and GSE154778 datasets.

Humanized dual-targeting antibody-drug conjugates specific to MET and RON receptors as a pharmaceutical strategy for the treatment of cancers exhibiting phenotypic heterogeneity.

Cancer heterogeneity, characterized by diverse populations of tumorigenic cells, involves the occurrence of differential phenotypes with variable expressions of receptor tyrosine kinases. Aberrant expressions of mesenchymal-epithelial transition (MET) and recepteur d'origine nantais (RON) receptors contribute to the phenotypic heterogeneity of cancer cells, which poses a major therapeutic challenge. This study aims to develop a dual-targeting antibody-drug conjugate (ADC) that can act against both MET and RON for treating cancers with high phenotypic heterogeneity.

Basic helix-loop-helix ARNT like 1 regulates the function of immune cells and participates in the development of immune-related diseases.

The circadian clock is an internal timekeeper system that regulates biological processes through a central circadian clock and peripheral clocks controlling various genes. Basic helix-loop-helix ARNT-like 1 (), also known as aryl hydrocarbon receptor nuclear translocator-like protein 1 (), is a key component of the circadian clock. The deletion of alone can abolish the circadian rhythms of the human body.

High-throughput methylation sequencing reveals novel biomarkers for the early detection of renal cell carcinoma.

Purpose: Renal cell carcinoma (RCC) is a common malignancy, with patients frequently diagnosed at an advanced stage due to the absence of sufficiently sensitive detection technologies, significantly compromising patient survival and quality of life. Advances in cell-free DNA (cfDNA) methylation profiling using liquid biopsies offer a promising non-invasive diagnostic option, but robust biomarkers for early detection are current not available. This study aimed to identify methylation biomarkers for RCC and establish a DNA methylation signature-based prognostic model for this disease.

Asthma-associated prostate enlargement and bladder smooth muscle hypercontractility: unveiling a potential link to LUTS.

Background: In male patients, benign prostate hyperplasia (BPH) and overactive bladder (OAB) secondary to BPH are the primary causes of Lower Urinary Tract Symptoms (LUTS). Recent clinical studies have reported an increased risk of LUTS, particularly severe LUTS conditions, in male asthmatic patients. However, the potential link and mechanism remain unclear.

Loss of Kmt2c or Kmt2d primes urothelium for tumorigenesis and redistributes KMT2A-menin to bivalent promoters.

Members of the KMT2C/D-KDM6A complex are recurrently mutated in urothelial carcinoma and in histologically normal urothelium. Here, using genetically engineered mouse models, we demonstrate that Kmt2c/d knockout in the urothelium led to impaired differentiation, augmented responses to growth and inflammatory stimuli and sensitization to oncogenic transformation by carcinogen and oncogenes. Mechanistically, KMT2D localized to active enhancers and CpG-poor promoters that preferentially regulate the urothelial lineage program and Kmt2c/d knockout led to diminished H3K4me1, H3K27ac and nascent RNA transcription at these sites, which leads to impaired differentiation.

Fungal keratitis caused by : a case report.

Background: We report a rare case of fungal keratitis caused by , a filamentous fungus that is widely distributed in soil and graminaceous plants.

After examination, the patient was diagnosed with a corneal ulcer of the left eye, and was given levofloxacin eye drops and levofloxacin ophthalmic gel.

Anlotinib combined with tislelizumab in the treatment of primary small cell neuroendocrine carcinoma of the prostate: a case report and literature review.

Primary small cell neuroendocrine carcinoma of the prostate is extremely rare, highly aggressive, and has a very poor prognosis, with an overall survival typically not exceeding one year. Standard treatment is generally based on the regimen for small cell lung cancer (SCLC), with guidelines recommending etoposide combined with cisplatin (EP regimen) as the first-line treatment. However, their therapeutic effects are limited.

Inhibition of SIRT4 promotes bladder cancer progression and immune escape via attenuating CD8 T cells function.

Background: Bladder cancer (BCa) is one of the most common malignancies of the urinary system and is characterized by a high recurrence rate and significant mortality. Sirtuin 4 (SIRT4), a member of the NAD-dependent deacetylase and ADP-ribosyltransferase family, is involved in regulating cellular metabolism, DNA repair, and longevity, potentially influencing tumor progression and immune escape. This study aimed to elucidate the role of SIRT4 in BCa.

Dysregulation of ubiquitination modification in renal cell carcinoma.

Renal cell carcinoma (RCC) is a malignant tumor of the renal tubular epithelial cells with a relatively high incidence rate worldwide. A large number of studies have indicated that dysregulation of the ubiquitination, including ubiquitination and dysregulation, is associated with the occurrence and development of RCC. This review focuses on several abnormal signaling pathways caused by E3 ligases and deubiquitinases.

Long non-coding RNA OSTM1-AS1 promotes renal cell carcinoma progression by sponging miR-491-5p and upregulating MMP-9.

Long noncoding RNAs (lncRNAs) have been recognized as essential regulators in various human malignancies. Hundreds of lncRNAs were known to be abnormally expressed in renal cell carcinoma (RCC) through a lncRNA expression microarray, among which lncRNA OSTM1 antisense RNA 1(OSTM1-AS1) was revealed as one of the most abundant lncRNAs. However, the function of OSTM1-AS1 in RCC remains unknown.

NSUN2-mediated R-loop stabilization as a key driver of bladder cancer progression and cisplatin sensitivity.

R-loops are critical structures that play pivotal roles in regulating genomic stability and modulating gene expression. This study investigates the interactions between the 5-methylcytosine (mC) methyltransferase NOP2/Sun RNA methyltransferase 2 (NSUN2) and R-loops in the transcriptional dynamics and damage repair process of bladder cancer (BCa) cells. We observed markedly elevated levels of R-loops in BCa cells relative to normal urothelial cells.

Single-Cell RNA Sequencing Reveals the Tumor Heterogeneity and Immunosuppressive Microenvironment in Urothelial Carcinoma.

Urothelial carcinoma (UC) can arise from either the lower urinary tract or the upper tract; they represent different disease entities and require different clinical treatment strategies. A full understanding of the cellular characteristics in UC may guide the development of novel therapies. Here, we performed single-cell transcriptome analysis from four patients with UC of the bladder (UCB), five patients with UC of the ureter (UCU), and four patients with UC of the renal pelvis (UCRP) to develop a comprehensive cell atlas of UC.

Primary ovarian insufficiency consequence of autoimmune diseases: a bidirectional two-sample Mendelian randomization study.
